I’m 26 and switching the direction I’m going in life. One of my childhood friends is an EMT at the moment and has been enjoying it, so I thought I would give it a try. He’s been helpful explaining things to me, but I don’t want to brother him with every question I have. So if you guys have any tips or tricks to help retain knowledge or what’s a good way to study, I would appreciate it greatly.
